Be it known that I, Aoifznxno BAIGN, a subject of the King of Great Britain, and residing at 439A Beaudry street, in the city of Montreal, in thev Province of Quebec, in the Dominion 'of Canada, have invented certain new and useful Improvements-in lneuinatie Tires; and I do hereby `declare that the following is a. full, clear, and exact description of the saine.

The invention relates to a pneumatic tire". for vehicles as hereinafter fully described with the aid of the accompanying drawings, in which the ligure is a cross section through the tire and rim.

The ob'ect of the invention is to rovide .l P a pneumatic tire in which the inner tube is thoroughly protected from puncture while giving all resilience of the ordinary pneu- Inatic tire.

A further object is tp increase the wearing qualities of the tread portion of the tire.

The invention consists in an ordinary tire provided with circumferential grooves integr l and within the casing or tire and nie-ans provided within said grooves to enra'ij'e the inwardly curved sides ot' an annuiin' plate.

Like numerals of reference indicate corl responding parts in the figure.

With reference to the drawings, l indi cates an ordinary wheel with a folly 2 and 3 is a riln secured to said telly to which the tire Jr according to the invention, is attached.

5 is a circular plate having two side ineinbers or flanges (5 inwardly bent at 7, forming a circular recess 8, said circular plate being placed within the tire.

i) are tongues integral with the tire l and projecting within said tire and l0 is a boss it'orxned on the inner end of said tongues 9, said boss en, ,rafinrT the circular plate 5.

l1 is the inner tube, said tube being pret'- erably bound in canvas, in order to pro tect it.

nlt is held that the 'tongues 9 which are within and integral with the tire sind the V-shaped slits l2 formed at each side, give the circular plate the side, tlie circular plate will play Within the space allotted therefor and will not damage or injure the .casing in any Way., The V-sliaped slits lQgive the tongues a certain amount of elasticity which will therefore transfer give to the inner tube, an eren pressure on one-half of its periphery.

It is believed that the', operation of the tire according to the invention will be fully understood from the foregoing description, i but it :nay be mentioned that the resilience is obtained through the compression of the inner tube when the tread member is pressed inwardly at any point,veoi`isequent upon the weight of the wheel.

W hat 'l claim is:

l. A pneumatic tire coniprisinb a shoe adapted to be attached to a wheel "elly, and an annular armor plate in raid shoe having a curved inwardly extending flange at eachside, said shoe being formed with an annnf lar space arranged radially inside of each flange, whereby the plate may inove inwardly.

2. it pneumatic-tire comprising a shoe formed with an annular space, which in a,Y

transverse section of the shoe appears as a. narrow part having an venlargemeirt at each end arranged inwardly of the narrow part,A and lateral flange at eacli side extending into the corresponding cnlargenient,=whereb the plate may nxove inwardly without any inding ot' a llange in -the shoe.
